Product Warranty

We warrant to you, the original purchaser, that each of its products will be free from

defects in materials and workmanship for two years from the date of purchase.

This warranty does not apply to any products which have been repaired or altered by

persons other than repair personnel authorized, or which have been subject to misuse,

abuse, accident or improper installation. We assume no liability under the terms of

this warranty as a consequence of such events. Because of high quality-control

standards and rigorous testing, most of our customers never need to use our repair

service. If any of products is defective, it will be repaired or replaced at no charge during

the warranty period. For out-of-warranty repairs, you will be billed according to the cost of

replacement materials, service time, and freight. Please consult your dealer for more

details. If you think you have a defective product, follow these steps:

1. Collect all the information about the problem encountered. (For example,

CPU type and speed, products model name, hardware & BIOS revision

number, other hardware and software used, etc.) Note anything abnormal

and list any on-screen messages you get when the problem occurs.

2. Call your dealer and describe the problem. Please have your manual, product,

and any helpful information available.

3. If your product is diagnosed as defective, obtain an RMA (return material

authorization) number from your dealer. This allows us to process your good

return more quickly.

4. Carefully pack the defective product, a complete Repair and Replacement

Order Card and a photocopy proof of purchase date (such as your sales

receipt) in a shippable container. A product returned without proof of the

purchase date is not eligible for warranty service.

5. Write the RMA number visibly on the outside of the package and ship it

prepaid to your dealer.

1. Getting Started

1.1 Safety Precautions

Warning!

Always completely disconnect the power cord from your

chassis whenever you work with the hardware. Do not

make connections while the power is on. Sensitive

electronic components can be damaged by sudden power

surges. Only experienced electronics personnel should

open the PC chassis.

Caution!

Always ground yourself to remove any static charge before

touching the CPU card. Modern electronic devices are very

sensitive to static electric charges. As a safety precaution,

use a grounding wrist strap at all times. Place all electronic

components in a static-dissipative surface or static-shielded

bag when they are not in the chassis.

1.2 Packing List

Before you begin installing your single board, please make sure that the

following materials have been shipped:

1.4 Manual Objectives

We have tried to include as much information as possible but we have not duplicated

information that is provided in the standard IBM Technical References, unless it proved to

be necessary to aid in the understanding of this board.

We strongly recommend that you study this manual carefully before attempting to set

up EPX-EHLP or change the standard configurations. Whilst all the necessary

information is available in this manual we would recommend that unless you are

confident, you contact your supplier for guidance.

Please be aware that it is possible to create configurations within the CMOS RAM

that make booting impossible. If this should happen, clear the CMOS settings, (see

the description of the Jumper Settings for details).

If you have any suggestions or find any errors regarding this manual and want to inform us

of these, please contact our Customer Service department with the relevant details.

2.2 Jumper and Connector List

You can configure your board to match the needs of your application by setting jumpers. A

jumper is the simplest kind of electric switch.

It consists of two metal pins and a small metal clip (often protected by a plastic cover) that

slides over the pins to connect them. To “close” a jumper you connect the pins with the clip.

To “open” a jumper you remove the clip. Sometimes a jumper will have three pins, labeled 1,

2, and 3. In this case, you would connect either two pins.

The jumper settings are schematically depicted in this manual as follows:

A pair of needle-nose pliers may be helpful when working with jumpers.

Connectors on the board are linked to external devices such as hard disk drives, a

keyboard, or floppy drives. In addition, the board has a number of jumpers that allow you to

configure your system to suit your application.

If you have any doubts about the best hardware configuration for your application, contact

your local distributor or sales representative before you make any changes.

The following tables list the function of each of the board’s jumpers and connectors.
